Component Approach
(Traditional) |
System Approach
(Pima Energy Methodology) |
| Select each component & size considering worst case loading and oversize |
Analyzes both Supply & Demand sides of a system to optimize total system performance |
| Simplifies design and selection, hence preferred route |
Requires more in-depth study where components of a process get configured to maintain high efficient performance over range of operating conditions |
| Sized on a particular design parameter |
Industrial systems do no operate under one condition all the time |
| Savings identified only for one component in isolation of its requirement for the associated process |
Maximum energy saving realized over the range of process operation |
| Process limitations and operations taken into consideration to give a more realistic idea on savings |
